	I am building a query that requires to show employess who signed a tool out on a specific date and never returned it. I am trying to use the Is Null function for the no return date, but get no data. Can someone show me how to do this? When I use DateValue 0000,00,00 it asks for a Date to be inserted... Thanks in advance.

	Set the datevalue to #1901-01-01# for no date. Drag the field on to your report > right click it > format field > common > click the x-2 to the right of supress. Enter the following; {table.field} = #1901-01-01# Regards, Ryan.

	Thanks! I did. Here is my statement: {EPD_ACCESS_HISTORY.ENTRY_DATETIME} > DateTime (2012, 01, 01, 01, 04, 01) and {EPD_ACCESS_HISTORY.EXIT_DATETIME}= DateValue (#1901,01 ,01#) and also: {EPD_ACCESS_HISTORY.EXIT_DATETIME}=#1901-01-01# but still get no results (???)

	Try CDate(0,0,0) for null date value. Sometimes it works
